just a regular michaels art store will do fine... ( i was really evil, they didnt lock the markers in a case and it was like "up for grabs" so i took one of each colors > <) now they found out that people have been doing that.... and locked it ) anyways, also a dickblick art store has the best deal for copics! ummm... yeh any bigger arts and crafts store... but if you go to a japanese manga store, i guanrantee that you will find copics there! try kinokunia at SF japan town...
